The Japanese is tempting, but I think I would rather wait till the week that all the products arrive, and then buy a giant brick of things like Cyclonic Rift and Heroic Intervention in ENG and JPN foil
Combining this with something like Birgi, God of Storytelling can keep your mana topped up to keep the party going
